To aZZ whom It may concern:

Be it known that I, ROY J`..V1NSOR, a citizen'of the United States, and resident of Milwaukee, in the. county of Milwaukee and State' of IVisconsin, have invented certain new and useful Improvements in Throttling Governors for Tractors; and I do liereby'declare that the following is a full, clear, and exact description thereof.

The invention -relatesto vde vices for tightening a fan belt on ya 'motor vehicle and tlirottling the intake of explosive mixture tractors. e

It comprises a Ith'rottling'.y governor, the case'of which forms an'idler pulley ada ted to tighten a fan belt. Means influence by a` spring are provided for supporting the pulley for tensioning operation, and means are 'provided for cooperatingwith the gov- Aernor to controla throttle.-

A primary object of the invention isfsimplicity of construction, and ease of manufacture.

` The partsarefadapted'to perform a dual function. `The governor c'a'se operates to lioufse the governor and to tensionv the belt and the 4supporting means. for-the case supports, also the'inechanisin for controlling the throttle.A

i j .'A very important object of theinvention .ern'or in place.

is readiness and convenience 'of installation. The mechanical operation of the timer is not disturbed nor alteredin any manner,

' the vmotor is notretimed, the/location of the .timer is not changed, and the regular but'-4 terfly -valve, gas throttle .and othery levers y remain intact; no holes `are drilled'. The Ymanner of installation is simple, not calling for aneXpert'nieclia-nic. T he mere loosening and-tightening of two cylinder head cap screws suffice forpositionin'gfthe gov-4 In addition to its functions in controlling themotor, the governor' performs the ad` yditional function o f acting'as a beltptightener. The governor case forms the .idler pulley, running against'the slack side of the belt. Thecase is light -in weight and reqiiii-es very slight pressure lagainst the belt tol drive it. The tensionof. aspring holds the governor tightly against' the fan belt and takes up the slack as the belt, stretches. This prevents" any possible slippage of l which:

either governor' or fan.v A 'water or voil soaked belt will not effect its operation.-

lVith the above and other objectsin view which will appear as the description p'ro.` ceeds, my invention resides .inthe novel construction, combination and arrangement of parts substantially as hereinafter de-x scribed and more particularly deined by I the appended claims, it beingunderstood that'such changes in the precise embodiment of the herein disclosed invention may be: inade as come -withinA the scope of the claims. In -the accompanying drawing,` I have illustrated lone complete' exam-ple of. Vthe physical embodiment of the presentinvention constructed accordingtol the-best mode I :have vso far devised forthe' .practical ap plication of the principles' thereof, and in Figure 1 is a side elevation of the ins tal.4 lation, parts being shown .1n section. l

"Ifo cylinder head 10, support-11 is se cured by means of 4cap screws l12-1 2. It4 carries bolt 13 on which armlll'is pivoted .and prevented from movement on" the longitudinal axis thereof,l by theli'ead of'the bolt. The arm is provided4 with apsocket portion 15, apertured and o erating to ,support governor case 16 Whic contacts-'with the-fan belt 17 and rotates O11 bearings 1 8..

.threaded relation' with cup v26. ing nut' 30 locks screw 28 securely( Plunger.' 2'4" lbears Aagainst spring 31, 'and-"moves `the upper arm'of lever` 32l rearwardly, the arm pivoting at 32 on lug 3 The end of the lower. arm-carries a contact 33, ,adapted tocooperate with the end 34 of spindle 35,

provided, with a collar '36, against which fingers 37 of the governor. are adapted to.

Contact the fingers moving rearwardly when weights 38 aredirected outwardly .by centrifugal force, .the weights being integral .Withfingers 37 and' the parts rotating on pivots 39,`so that on rapid travel of belt 1,7, .the -governor operates to move Contact 3,3 rearwardly and arm. 32 forwardly,- the arm -being secured -to rod 40, its position o n the rod being-determined by jamb nut 41.

lRod 40 .is secured by pivot 41to lever 42 which operates-thru the medium of spindle 43 to control the position ofbutterfly 44 in auxiliary connection '45,Y which received between throttlingvalve housing 46 and in- '.takefA manifold 47, the parts being secured together. by studs 48. Extension 49v is positioned. in hot air tube- 50, Thus mixing chamber 51, the regular butterfly, the gas throttle and other levers. and the various f jmechanical parts, remainsubstantially ulialtered. t

It will be noted that the movement of arm 14 in taking up slack of Vbelt17, does not disturb the controlling operation' of the governor, the relation of lever arm- 32 androd '40 being such as to permit the accurate and reliable control ofthe throttle in spite of lateral movement of the governor-ease. Also when the governor is operative and lever arm 32 moves rod 40 to. control the throttle,

' the governor case 16 continues performing its tightening action. The case is light vin Weight and v requires very sllglit pressure against the belt to drive` it. -This .makes the/ governing action reliable. -As tlfie' belt stretches, the slack is automatically taken up. There is no possible 'slippage' of governor or fan. `Below a certain speed, thev con trol of the motor is bythe handthrottlefas .in the normal operation.

I claim 1. The combination of a. belt tightener ini cluding a pivotallymounted support, 'a pul- -Wisconsim ley carried thereby, a governor driven by saidpulleyand having an operative portion locatedad'jacent the pivot point of `said support, and means connected with such operative portion and extending outwardly therefrom. A

device` of the type described, the combination of a belt, a support pivotally mounted at one end,.an idler pulley carried port, and a'control link'extending from the movable portion of said means, whereby the 'positionof said control link is controlled by said governor-and is substantially independ- 'ent of the angular portion' of said support. y 3. In a device of the class described, the combination of an idler vpulley operative for tightening. a' belt, said -pulley being hollow, a governor therein, a support for said pulley' and said governor, means for maintaining" said pulley in-contactswith'a belt, and means tcooperating with said governor vfor throttling the supply of explosive mixture.

4. ',In`a ldevice 'of the classdescribed, the

combination of a pulley for ti, 1,fhteninga support carrying said pulleyr fand governor at it's.free:end, means plvotally supportmg belt, a governor driven thereby, a swinging 4 said swinging, support, means tending to rocl'rsaid swinging support one. direction, a lever pivoted to said swinging support and having its position controlled by said governor', and control meanscontrolled by saidlever, and extending 'outwardly therefrom. In ,testimonythat I claim the foregoing AI have hereunto set my hand at Milwaukee,

in the4 county ofMilwaukeefa'nd State of ROY J. VVINSOR.
